The compressor will then raw air in through the valves 29 and 51 so thatthe compressed air will be forced outward through the exhaust manifold30, the pipe 31, the pi e 32, the valve 33 (which is normally open) t epipe 34 and ,the check valve 36 into the tank 35.

A. branch pipe 101 extends from the pipe 89a and is provided with apressure indicating gage 102.

In order to permit the plunger rod 82 to loperate in the mannerdescribed and operate the clutch member 7 3, air is exhauste from thecylinder 80 through the pipe 87', the pipe 47 and the valve 39 which isnormally open. When the combined air motor and compressor 22 is`operating to compress air for storage in the tank 35, air is drawn intothe cylinders of the compressor 22 through the intake valves 39, intakemanifold 41, pipes 42 and 47, valve 38 and port 40.

As soon as air pressure within the tank 35 insucient to close the valves91 and 92, air within the cylinder 88 will act on the plunger 89 toforce the rod 82 toward the compressor 22 so that 'the clutch willassume a neutral position as shown in Figure 10 of the drawin s.

n order to restore air to the cylinder 88, the tank 35 is provided witha valve 95a which is in communication with the pipe 89e through a branchpipe 955. This valve 95a includes a spring influenced valve member 95awhich is unseated when pressure within the tank 35 reaches apredetermined degree. The valve member 95o however'is not unseated untilafter the valve members 94 of the valves 91 and 92 are seated. This isdue to the fact that the springvof the valve 95e is stronger than theszings of the valves 91 and 92. It will thus seen that after the valves91 and 92 are closed and pressure within the tank 35 continues toincrease, the valve 95a will be open and pressure will be restoredwithin the tank 88 to move the plunger 89 in this tank to neutralposition, as shown in Figure 10. The, plunger rod 82 1s at the l1m1t oflts stroke in this figure under the action of the plunger 89.v However,the rod 82 may move further in a direction toward the compressor 22under the action of air upon' the plunger 81 within the cylinder 8 Inorder to operate the combined air motor and compressor 22 to start theoperation of the. motor 20, the rocker arm 48 is operated to close thevalves 33 and 39 and open the va'lves 44 and 45. When this occurs aircontrolled by a manually operated valve 103 will pass from the tank 35through a pipe 104, the

pipe 46, the valve 44, the pipe 42, the intake manifold 41 into thecylinders of the combined air motor and compressor 22. Air will videdwith exhaust from these cylinders through the pi 31 and the valve 45,the valves 33 and 39 bein closed. At the same time, air from the pi 42will cylinder and act upon the plunger 81 to force the rod 82 furthertoward the compressor 22, this further movement being permitted by theloose connection between the rod 82 and the plunger 89.V This furthermovement will move the clutch member 7 3 to the left of the positionshown in Figure 10 of the drawings-so that the clutch member will engagethe clutch late 79. The motor 20 wi l then be driven om the startingmotor 22 directly through the shaft section 61, the clutch member 73,the clutch plate 79, the shaft section 62 and the gears 59 and 58.

A pressure indicating gage 105 is connected by means of a pipe 106 withthe pipe 104.

The pipe 104 is in communication with a exible pipe or hose 107. Theinner end of thisl pipe or hose is provided with a manually operatedvalve 108 so as to admit or cut of pressure. 'lhe outer end of the pipeis proa valve 109 such as is commonly used for the inflation ofautomobile tires.

An additional manually operated valve '110 is provided at the outer endof the hose 107. Pressure from the tank 35 may thus be utilined toinflate the tires of the automobile.

In'addition, air from the tank 35 is utilized to force gasoline from thegasoline supply tank 111 to the carburetor 21. For this purpose, thepipe 104 is provided with a spring inuenced valve 112 which controlscommunication through a pipe 113 to the tank .111. rlhe pipe 113 hasextending therefrom a branch pipe 1.14 which isprovided with a springinfluenced exhaust valve 115. The valves 112 and 115 are controlled by alever 116 which is mounted on a rock shaft 117 and this shaft hassecured thereon an arm 118 which is located between the valves 112 and115.

By movin the lever 116 in the direction of the arrow s will be o ened toadmit air tothe 'tank 111 so as to orce the gasoline to the carburetorthrough a pipe 119. By moving the lever 116 in a reverse direction, thevalve 115 may be opened to exhaust air from the tank 111.
